I could see how it would be helpful for people who don't necessarily know they have sleep apnea. I also recently read about someone who quit smoking weed, and their sleep tracking changed dramatically while they detoxed. With my Garmin, that and the Stress tracker usually let me know 1-2 days ahead of time that I'm getting sick, before I even feel it. My sleep quality plummets, and my physiological stress is at like 80%+.
